TIRE AND TIRE-CARRYING RIM FOR THE WHEELS OF MOTOR-CARS, &c.

skilled in the art to which it appertains to make and use the same.

This ,invention relates to tires und tirecarrying rims for the wheels of motor cars and other vehicles, and more particularly to an improved construction of what is known as a 'security band. Asis well known annular security bands are sometimes employed with circumferentiallv divisible tire carlgviug rims, or with rims having detachable ianges, instead of the security bolts usually employed with solid or undivided rims. Various forms of such bands have been heretofore proposed. some for instance made of metal, some of india rubber only, and others of india rubber and fabric either with or without a metal insertion.

The present invention has for its object un improved construction of security band which while heilig substantially incompressible in a lateral direction shall at the same time be flexible and inextcnsiblc longitudinally.

According to this invention the security band is formed of a plurality of concentricallv disposed layers of canvas and of india.- rubber vulcaniaed together. and the band is rendered inextensible bv the insertion in it during manufacture of oops of iano wire. The band is formed endless an a hole is made throufvh it to accommodate the valve tube. The band is suitably reinforced near the vulve hole. 'l`he band is made wedge shaped in cross section and the piano wire is placed near the edges of the upper side or wider ortion thereof and passes on either side ofpthe valve hole. Each of the piano wire hoops consists of a single strand wound into several convolutions under even tension and the two ends nre securely joined together.

The construction of a band according to Specification of Letters Patent.

Application led November 13, 1909. Serial No. 527,803.

vThe band is wedge shaped in cross secti Patented Mur. 21, 1911 this invention is illustrated by the accom panyingl drawing in which,-

Figure 1 is a cross sectional elevation o the security band shown applied to a tir mounted in a detachable and divisible rin the band being cut at about the line A-l Fig. .2 is a side elevation of a por a tire and rim, the inner periphery of th band being here .shown uppermost. Fig. is a cross sectional elevation of the band a the valve hole and taken on the line C-l Fig. 2, the outer peri hery of the band b( ing uppermost, and fig. 4 is a cross ser tional elevation of the band as, it is prefei ably constructed throughout the greater por tion of its length. f

Like reference numerals indicate lik parts in the several figures of the drawin` Referring to the drawing, 1 is the securit band, 2. 2 the edges of the tire cover and I1 3 the sections of a divisible tire carryin riln. As shown in Fig. 1. the rim section are held together by n bolt 4 passing throng a lug 5 on the rim section 3 and taking int a threaded hole in a lug 6 on the rim sectio 3. The rim as a whole is moved to an from its position on the wheel, and held i place thereon, by a jack-bolt 7. The par ticular construction of the rim sections an securing means formano part of the presel invention and is only shown to clearly illu` trate the ap lication of the security ban forming the invention to a tire and rim.

The security band 1, formin the subje( of this invention, is formed as s own ofcor centrically disposed layers of canvas 8 an of india-rubber 9 of suitable density vulcai ized together, and it is rendered inextensib by the insertion in it during manufacture t piano wire hoops 10. Any number of alte nate lavers of canvas and india-rubber ma Ibe use and all the.lavers of canvas ma extend through the whole length of th band, or only some of them may so exten the remainder extending only for some di tance on either side of the valve hole an terminating at say 8 to 10 inches therefrox and in the construction shown in the drm ing the major portion of the band consists india-rubber with a layer of canvas at or ne the inner and outer peripheries of the an the band at the valve hole having seve k s i,

ywddit-ional reinforcing layers of canvas exending1 for some inches on either side of the lve ole and being intermediate of the Q ngth of the band. The two hoops of piano gire 10, inserted in the band during manutcture, consist each of several eonvolutions or outer peripheral ed es of the band id pass on either side of tie valve hole as hewn, the ends of the wire forming each oop being securelyr joined together in any 'lf'iitable or known manner.

The band when in use is placed between e edges 2, 2* of the tire cover and is of a ameter just suflieiently larger than the bed ,the rim that it can be put into position yith,the tire and air tube when one side or ange 3 of the rim is removed. As the band inextensible and substantially incompresjble, when the two parts of the rim are `VIawn together by the bolts 4 0r other securg means said band will wedge the beads of e same time form a water-tight joint be- 'een such band and the outer cover and vl'yers extending throughout the whole;

7a sin le strand wound under even tension, tl are oeated near or toward the outer corf e outer cover tightly under or into the i ges or lips of the rim section 3, 3 and at g BEST AVAILABLE COPY thus keep moisture away from the inner tube.

Any of the well known 0r suitable alternatives for 1ndiarubber, canvas and piano wire may be combined in the manner set forth above in the manufacture of a security band without departing from the object of this invention.

What 1 claim as my invention and desire to secure by Letters Patent is security band for fastening pneumatic tircs. consisting of an inextensi 1e and substantially incompressible body comprising a plurality of concentric layers of canvas and india-rubber vulcanized together, and metallie reinforcing hoo s incorporated in the bund body during tie manufacture thereof and arranged at points ad`acent to the lateral edges and'the wide ace thereof, sad hoopsl each being formed of a single wire strand wound into loops or convolutions under even tension.

ln testimony whereof I atlix my signature7 in the presence of two witnesses.
